Baghdad suicide bomber kills at least 15

A suicide bomber set off an explosive vest in a busy Baghdad square crowded with rush-hour commuters early Monday, killing at least 15 people and wounding dozens, officials said.

The attack took place in Adan Square, in a predominantly Shia part of the capital, and appeared to be the latest in a near-daily string of attacks carried out by Sunni Islamic extremists targeting the country's Shia majority.
